ACETYLENE-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 784,687, dated March 14, 1905.

Application filed September 16, 1904.

To all whom it may concern;

Be it known that we, SAMUEL L. KIs'rLER, residing at Los Angeles, and HENRY SYMoNDs, residing at Longbeach, in the county of Los Angeles and State of California, citizens of the United States, have invented new and useful Improvements in Acetylene-Gas Burners, of which the following is a specification.

Our invention relates to a burner more especiall y designed to produce heat than light; and the object thereof is to produce an acetylenegas burner of simple construction that will produce a large amount of heat. We accomplish this object by the burner described herein and illustrated in the accompanying drawings, in which Figure 1 is a vertical central section of one of the burner-tips and a cross-section of a portion of the supply-chamber. Fig. 2 is a plan view of the supply-chamber and burner-tips.

In the drawings, 1 is the usual mixing-tube, provided with the usual air-inlet and spud, which supplies the gas to the burner, these latter elements not being shown. The mixing-tube opens into the annular supply-chamber 2, which is preferably semicircular in crosssection, as shown in Fig. 1. The casing of this chamber is preferably cast in two parts, which are secured together by bolts 3, the top plate 4 being an annular plate provided with burner-tips 5, of which there may be any desired number. a series of circular chambers 6, 7, 8, and 9 of different diameters, which we have found by experiment produce the best result when made about the proportion shown in Fig. 1, the diameter of the upper section 6 being ten thirty-seconds of an inch, that of section 7 being eleven thirty-seconds of an inch, that of section 8 being twenty-three sixty-fourths of an inch, and the largest diameter of section 9 being nine-sixteenths of an inch, and the total height of the tip being five-eighths of an inch from the bottom of chamber 8 to the top of chamber 6. The top wall of chamber 6 we have found should be one thirty-second of an inch thick and should be slightly globular, as shown have used.

These burner-tips consist of Serial No. 224,768.

in Fig. 1, and the gas-orifice ll, leading therefrom, is formed by cutting through the top, in the center thereof, to the vertical wall with a fine hack-saw. Across the bottom of chamher 9 is a fine wire-gauze screen, which is held in place by having the edges thereof placed between the upper and lower sections of the supply-chamber.

Fig. 1 shows the proper proportion of a burner-tip which we have found by practice to produce the most satisfactory results of any burner-tip that we have tried in our experiments, of which we have made a great many, and is drawn to a scale which is four times as large as the actual size of the tip which we We have found by our experiments that the proportions may be varied within reasonable limits, but that the above proportions produce the best results. A burner thus constructed provides a simple and efficient heat-producing acetylene-gas burner that will produce a wide flat blaze and will produce more heat units than any other form of burner that we were able to construct during our experiments or that we have ever seen used for that purpose. The successive enlargements of the chambers of the burnertips, as shown in Fig. 1, permit of the full force of gas-pressure to pass out of the gasorifice at the top, which orilice being very narrow prevents back l'iring.

By using a sutlicient number of tips with the orifice on a line substantially parallel with the outside of the supply-chamber and placing them sufficiently close together, as shown in Fig. 2, the flame produced by the various tips impinge, thereby making a substantially circular flame, which is a great improvement over those burner-tips which have unobstructed outlets, thereby producing detached jets of flame.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In an acetylene-gas burner for producing heat, a burner-tip consisting of a plurality of circular chambers of increasing diameter from the top toward the bottom, the top chamber having anarrow slitted orifice, extending from one side wall to the other and passing centrally across the top of said chamber through the top plate thereof.

2. An acetylenegas burner comprising a mixing-tn be,a supply-chamber into which said mixing-tube opens, burner-tips connected and opening into said supplychamber,said burnertips having narrow slitted outlets, and being composed of a plurality of circular chambers of increasing diameters toward the bottom.

3. An acetylene-gas burner comprising a mixing-tube,asupply-chamber into which said mixing-tube opens, burner-tips connected and opening into said supply-chamber,said burnertips having narrow slitted outlets, and being composed of a plurality of circular chambers of increasing diameters toward the bottom,

wire screening intermediate said burner-tips and supply-chamber.

4. Anacetylenegas burner comprising a mixing-tube, an annular supply-chamber into which said mixing-tube opens,burner-tips connected and opening into said supply-chamber, said burner-tips having narrow slitted outlets, and being composed of a plurality of circular chambers of increasing diameters toward the bottom, wire screening intermediate said burner-tips and supply-chamber.

In witness that We claim the foregoing We have hereunto subscribed our names this 8th day of September, 1904.
